Parked domain -> active

I have 2 domains in cPanel 11.34.2 (build 4) - cPanel Pro 1.0 (RC1): the main one which is currently in use and the parked domain under Domains -> Parked domains. How can I make it active and point that parked domain into specific directory, let say public_html/xyz/ so that directory will be accessible directly by parkeddomain.com? Thanks.
